Abstract: Sunflower is the most important source of edible oil and fourth-largest oilseed crop in the world. The purpose of this study was to investigate the effect of using two organic fertilizers from various sources (compost coupled with biofertilizer (CCB), filter mud cake (FMC)) and comparing them to conventional inorganic fertilizers in their effect on the quality of sunflower seeds, sunflower oil, and soil properties. The data showed that the highest value of dry weight, plant height, disk dry weight in addition to chlorophyll content, and phenolic secondary metabolites in oil was measured after the application of inorganic fertilizer, while the use of organic fertilizer contributed to a substantial increase in the production yield of sunflower seeds, oil, and a high stalk yield compared with inorganic treatment. Oils produced from organic fertilizer (CCB and FMC) gave higher blue color values than inorganic ones and the most transparent oil was inorganic while the organic treatments produced darkest oils. The results for chemical composition of sunflower seeds showed nonsignificant differences for protein and ash among all treatments while a significant difference with regard to oil content was recorded, in which the FMC recorded the highest oil content followed by compost (CCB), and finally came the inorganic treatment. Organic fertilizers are a valuable source of organic material and nutrients essential for plants and can be safely used for soil, crops, and the environment.
